The author manages to touch upon just about every major philosophical issue that has ever commanded serious attention.  The extraordinary thing is that far from this resulting in a superficial treatment, he manages to throw light upon ever one of the issues he takes up. This strikes me as an extraordinary feat. It is partly due to the neat organization of the material around particular subject matters, and partly due to the fact that the author has a very clear understanding ot the problems and the kinds of solution that have been proposed. So the upshot is not just a book for undergraduate survey courses, but something which everyone interested in philosphy can read with profit.
